So it was all the more shocking for her old coach and the Walnut community to learn of the Sunday night killing of Quan, 28, and her fiance, Keith Lawrence, 27, who was a basketball star too.

Each was shot multiple times, and authorities said they have tentatively
ruled out the possibility of the crime being a murder-suicide or
motivated by robbery.

Autopsy results due back Tuesday could provide more clues into the slaying of the Cal State Fullerton coach and Lawrence, a public safety officer with USC. The couple's bodies were discovered in their car on the top level of the parking structure at their upscale, high-security condominium complex near UC Irvine.

The two became engaged in January, a family member said, and had recently moved into the condo complex. They met at Concordia University in Irvine, where they both played basketball and earned their degrees.
